Detailed Description
As described above, when a communication apparatus handles multitasking, there is a case where a certain task is allocated for a short time.
For example, in the first scenario, for a certain communication device, the following functions need to be performed simultaneously: open the wifi function, use the online music of bluetooth headset broadcast to and search and connect the bluetooth bracelet, wherein, open the wifi function and carry out the wifi task for this communications facilities's wifi module, use the online music of bluetooth headset broadcast to carry out A2DP task for this communications facilities's bluetooth module, search and connect the bluetooth bracelet and carry out BLE SCAN task for this communications facilities's bluetooth module. Wherein, bluetooth module and wifi module can be integrated on a chip. At this time, the time-sharing situation of the communication device for the three tasks is: wifi (30%) + A2DP (50%) + BLE SCAN (20%). It can be seen that, since wifi tasks and A2DP tasks are prioritized over BLE SCAN tasks, the time of BLE SCAN tasks is sacrificed to maintain wifi tasks and A2DP tasks, accounting for only 20%.
For another example, in the second scenario, for a certain communication device, the following functions need to be executed simultaneously: the method comprises the steps of starting a wifi function, using a Bluetooth headset to conduct WeChat voice call, and receiving information of other communication equipment, wherein the wifi function is started to execute a wifi task for a wifi module of the communication equipment, the Bluetooth headset is used to conduct WeChat voice call to execute an eSCO task for a Bluetooth module of the communication equipment, and the information received by the other communication equipment is used to execute a BLE SCAN task for the Bluetooth module of the communication equipment. At this time, the time-sharing situation of the communication device for the three tasks is: wifi (56%) + eSCO (33%) + BLE SCAN (11%). It can be seen that, since wifi tasks and eSCO tasks are prioritized over BLE SCAN tasks, the time of BLE SCAN tasks is sacrificed to maintain wifi tasks and eSCO tasks, accounting for only 11%.
However, with the development of bluetooth technology, the time for the communication device to execute the BLE SCAN task needs to reach about 40%, and in the above two scenarios, the time for executing the BLE SCAN task is not sufficiently allocated and is occupied by other tasks, so that when the BLE SCAN task is executed, the problem that the specified device cannot be searched often occurs.
Therefore, in some scenarios, the communication device needs to handle multiple tasks, and at this time, the communication device cannot simultaneously guarantee that multiple tasks are allocated correspondingly enough time to execute, that is, cannot simultaneously perfectly compromise multiple tasks.
In view of the above, the present invention provides a bluetooth communication method to solve the above problems. In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and the detailed description.
Fig. 1 is a flowchart illustrating a bluetooth communication method according to a first embodiment of the present invention. The execution subject of the bluetooth communication method is a first communication device, and the first communication device may be a bluetooth chip or a combined chip (including a bluetooth module and a wifi module), or a device including a bluetooth chip, or a device including a combined chip, such as a smart phone.
In an example, the first communication device may determine whether to start executing the bluetooth communication method in a preset manner, for example, API/host setting/tci command/hci command. For example, the first communication device may determine to start to execute the bluetooth communication method through an tci _ colorloader _ enable command. Wherein the Host Layer of the first communication device transmits tci _ colormaker _ enable command to a Link Layer (LL), and then the bluetooth communication method is performed.
Specifically, as shown in fig. 1, the bluetooth communication method includes:
step 110: the first communication device establishes a bluetooth connection with the second communication device.
The first communication device needs to perform a plurality of tasks, for example, a wifi task, an A2DP (Advanced Audio Distribution Profile) task, an eSCO task, a BLE SCAN task, and the like in the above scenario, so as to perform a plurality of functions. The second communication device may be a bluetooth chip or a combined chip (including a bluetooth module and a wifi module), or a device including a bluetooth chip, or a device including a combined chip, such as a smart phone, etc. The second communication device may be in a state where the task is not being performed or in a state where the task is being performed.
In an example, the second communication device may determine whether to assist the other devices in performing some task in a preset manner, for example, Setting UI/API/host Setting/tci command/hci command. For example, the second communication device may pass an tci _ colorloader _ enable command to assist the first communication device to start executing the bluetooth communication method. Wherein the Host Layer of the second communication device sends tci _ priority _ enable command to a Link Layer (LL) to assist the first communication device to start executing the bluetooth communication method.
Step 120: the first communication device communicates with the second communication device through a Bluetooth connection to distribute a part of a plurality of tasks to the second communication device to execute, wherein the part of tasks comprises a scanning task, such as Scan/Inquiry.
The first communication device does not sufficiently allocate time to part of tasks, so that the part of tasks cannot be completely executed, or the execution result of the part of tasks is poor. The time of the partial task is not enough, which may be because the priority level of the partial task is low, or may be a preset time.
Wherein the remaining tasks of the plurality of tasks may be executed by the first communication device itself, or a part of the remaining tasks may be executed by the first communication device itself and another part may be executed by the other communication device.
In an example, the first communication device and the second communication device are both provided with a component for playing music, and part of the plurality of tasks may further include the A2DP task.
Step 130: the first communication device receives the result of the second communication device performing the portion of the task from the second communication device via a bluetooth connection.
Wherein, the result that the second communication equipment carries out the scanning task is the search result, and the search result includes: and the searched identifications of the communication devices in the vicinity of the first communication device and the second communication device. In this embodiment, the distance between the first communication device and the second communication device is smaller than the preset distance, so that the first communication device and the second communication device are close to each other, and thus the search result obtained when the second communication device executes the scanning task is substantially the same as the search result obtained when the first communication device executes the scanning task by itself, so that the first communication device can use the second communication device to execute the search result obtained when the scanning task is executed.
In this embodiment, the first communication device establishes a bluetooth connection with the second communication device, and performs communication through the bluetooth connection, so that part of tasks of the plurality of tasks are allocated to the second communication device for execution, where the part of tasks includes a scanning task, and the remaining tasks are executed by the first communication device itself, and then the first communication device receives a result of the execution of the scanning task.
The effect of the present invention is explained below by taking a specific scenario as an example, in which it is assumed that the second communication apparatus is in a state where no task is performed.
In the first scenario, the first communication device needs to execute a wifi task, an A2DP task, and a BLE SCAN task, and after the first communication device executes the bluetooth communication method according to the embodiment of the present invention, the tasks executed by the first communication device are respectively: wifi task, A2DP task and BLE link task, the task that second communications facilities executed respectively is: BLE SCAN task and BLE link task, wherein the BLE link task establishes the bluetooth for between first communications facilities and the second communications facilities and is connected, and at this moment, the time distribution condition of above-mentioned task is:
the time allocation situation of the first communication device to the task executed by the first communication device is as follows:
wifi(35％)+A2DP(55％)+BLE link(10％)，
the time allocation situation of the second communication device to the task executed by the second communication device is as follows:
BLE SCAN(90％)+BLE link(10％)。
in the second scenario, the first communication device needs to execute a wifi task, an eSCO task, and a BLE SCAN task, and after the first communication device executes the bluetooth communication method according to the embodiment of the present invention, the tasks executed by the first communication device are respectively: wifi task, eSCO task and BLE link task, the task that second communications facilities executed respectively is: BLE SCAN task and BLE link task, wherein the BLE link task establishes the bluetooth for between first communications facilities and the second communications facilities and is connected, and at this moment, the time distribution condition of above-mentioned task is:
the time allocation situation of the first communication device to the task executed by the first communication device is as follows:
wifi(35％)+eSCO(55％)+BLE link(10％)，
the time allocation situation of the second communication device to the task executed by the second communication device is as follows:
BLE SCAN(90％)+BLE link(10％)。
it can be seen that, in the two scenarios, the time allocation of the BLE SCAN task reaches 90%, and meanwhile, the time allocation of other tasks is also satisfied, that is, the first communication device can obtain the result of performing the BLE SCAN task and can perform other tasks only through the bluetooth connection established between the first communication device and the second communication device, so that the tasks in different scenarios can be performed perfectly, and a situation that the time allocation of a certain task is insufficient does not exist.
It should be noted that, the above example is illustrated by time division multiplexing of bluetooth and WiFi, and those skilled in the art can understand that the present invention is not limited thereto, and bluetooth and WiFi may also be frequency division multiplexed, and in a scenario of frequency division multiplexing of bluetooth and WiFi, the technical solution of the present invention may also be adopted.
Wherein step 110 further comprises: receiving an information packet broadcast by a second communication device, wherein the information packet at least comprises: indication information for indicating whether the second communication device is capable of performing a part of the task; the first communication device determines whether the second communication device can execute the part of the task according to the information packet, and establishes Bluetooth connection with the second communication device capable of executing the part of the task when the second communication device can execute the part of the task. The specific implementation of step 110 may be as shown in fig. 2, fig. 3 and fig. 4:
fig. 2 is a flowchart illustrating a bluetooth communication method according to a second embodiment of the present invention. On the basis of the first embodiment, the step 110 further includes:
step 1111: receiving a packet broadcast by a second communication device, wherein the packet comprises: indication information indicating whether the second communication device is capable of providing free resources, and indication information indicating a length of time that the second communication device is free of free resources that can be provided.
The idle resource is used to refer to an idle bluetooth communication band, that is, an idle bluetooth communication band when no bluetooth related task is executed. The idle bluetooth communication band may include a channel 37, a channel 38 and/or a channel 39, and the idle bluetooth communication band may also refer to other bluetooth communication channels.
In an example, the information packet may be an advertisement (advertise) message or a Connectionless Subordinated Broadcast (CSB) message.
Step 1112: and the first communication equipment determines that the second communication equipment can provide idle resources according to the information packet.
Step 1113: and the first communication equipment determines that the relation between the time length required by the first communication equipment to execute the partial task and the idle time length of the idle resource meets the preset condition according to the information packet.
In an example, the time length of the idle resource that can be provided by the second communication device in step 1111 may be expressed as: the proportion of time that an idle resource is idle to the time of one communication cycle. The time length required for the first communication device to execute the partial task by itself can be expressed as a ratio of the time occupied by the bluetooth communication frequency band for executing the partial task by itself to the time of one communication period.
In one example, the preset conditions include: the time length of the idle resource is longer than or equal to the time length required by the first communication device to execute a part of tasks, and/or the time length of the idle resource is shorter than the time length required by the first communication device to execute a part of tasks, and the difference between the two is smaller than or equal to a preset value, for example, the time length of the idle resource of the second communication device is 40%, the time length required by the first communication device to execute a part of tasks is 50%, and the preset value is 10%, at this time, the preset condition is satisfied.
Step 1114: the first communication device establishes a bluetooth connection with the second communication device.
When the relation between the time length required by the first communication device to execute the partial task and the idle time length of the idle resource meets the preset condition, the first communication device determines to establish Bluetooth connection with the second communication device and sends a response signal to the second communication device, so that the first communication device establishes Bluetooth connection with the second communication device. Wherein the reply signal may be a bluetooth connection setup request message.
When the relation between the time length required by the first communication device to execute the partial task and the idle time length of the idle resource does not meet the preset condition, the first communication device determines not to establish the Bluetooth connection with the second communication device and does not send a response signal, so that the first communication device does not establish the Bluetooth connection with the second communication device.
In an alternative example, step 1113 may not be performed, that is, the first communication device may establish a bluetooth connection with the second communication device as long as the second communication device can provide idle resources.
Fig. 3 is a flowchart illustrating a bluetooth communication method according to a third embodiment of the present invention. On the basis of the first embodiment, the step 110 further includes:
step 1121: receiving a packet broadcast by a second communication device, the packet comprising: the information indicating whether the second communication device is capable of providing the free resource, the information indicating the length of time that the free resource is free that the second communication device is capable of providing, and the information indicating whether the second communication device is capable of providing the adept function.
Wherein the excel function comprises at least: and a function of filtering the search result obtained by executing the scanning task. Specifically, the method refers to that the second communication device executes a scanning task to obtain a search result, and filters the search result according to a filtering condition sent by the first communication device, where the filtering condition may include: an identification of a device that the first communication device desires to scan for, and/or a signal strength indication of a signal strength that the first communication device desires to scan for has. In this way, when the filtering condition includes the identifier of the device that the first communication device desires to scan, the second communication device finds out, in the search result, the device identified by the identifier of the device that the first communication device needs to scan; when the filter condition includes a signal strength indication of a signal strength that the first communication device desires the device to scan to have, the second communication device finds, in the search result, a device whose signal strength detected at the time of scanning is higher than or equal to the signal strength indicated by the signal strength indication.
The excel function may further include: an address resolution function capable of resolving an address at which a certain device is searched for from a key (key) provided by the first communication device. For example, the first communication device is a mobile phone, which is already paired with its own private device (e.g., a bluetooth headset), and the bluetooth headset is a private device of the mobile phone, so that not all devices in the network can resolve the address of the bluetooth headset, but only the key (key) can resolve the address of the bluetooth headset. If the second communication device has an address resolution function, the second communication device can resolve the address of the bluetooth headset according to the key provided by the first communication device during subsequent scanning, so as to help the mobile phone to find the bluetooth headset.
Steps 1122-1123 are substantially the same as steps 1112-1113.
Step 1124: and the first communication equipment determines that the second communication equipment has the function of filtering the search result obtained by executing the scanning task according to the indication information indicating that the first communication equipment has the excellence function.
Step 1125: the first communication device establishes a bluetooth connection with the second communication device.
Specifically, when the relationship between the time length required by the first communication device to execute a part of tasks and the time length of idle resources meets a preset condition and the second communication device has a function of filtering search results obtained by executing scanning tasks, the first communication device establishes bluetooth connection with the second communication device. The specific way of establishing the bluetooth connection is the same as that in the above embodiments, and is not described herein again.
In an alternative, step 1124 may be that the first communication device determines that the second communication device has an address resolution function according to indication information indicating that the first communication device has a good function, and step 1125 may be that the first communication device establishes a bluetooth connection with the second communication device when a relationship between a time length required for the first communication device to perform a part of tasks and a time length for which idle resources are idle satisfies a preset condition and the second communication device has the address resolution function.
Fig. 4 is a flowchart illustrating a bluetooth communication method according to a fourth embodiment of the present invention. On the basis of the first embodiment, the step 110 further includes:
step 1131: the first communication device receives an information packet broadcasted by the second communication device, wherein the information packet comprises: indication information indicating a task being performed by the second communication device.
Step 1132: the first communication device determines whether the second communication device is performing the portion of the task based on the information packet.
Step 1133: the first communication device establishes a bluetooth connection with a second communication device that is performing part of the task.
Optionally, in step 1131, the information packet further includes: indication information indicating a length of time required for the second communication device to be performing the partial task. The length of time required for the second communication device to perform the partial task may be a ratio of time for occupying the bluetooth communication band to time for one communication cycle, which is expected for the partial task being performed by the second communication device. At this time, the method further includes the first communication device determining whether a relationship between a length of time required to perform the partial task on its own and a length of time required for the second communication device to be performing the partial task satisfies a preset condition.
In one example, the preset conditions include: the time length required by the second communication device to execute the partial task is greater than or equal to the time length required by the first communication device to execute the partial task; and/or the preset conditions comprise: the time length required by the second communication device to execute the partial task is less than the time length required by the first communication device to execute the partial task, and the difference between the two is less than or equal to the preset value, for example, the time length required by the second communication device to execute the partial task is 40%, while the time length required by the first communication device to execute the partial task is 50%, and the preset value is 10%, at this time, the preset condition is satisfied.
When the relation between the time length required by the first communication device to execute the partial task and the time length required by the second communication device to execute the partial task meets the preset condition, the first communication device determines that the Bluetooth connection is to be established with the second communication device, and sends a response signal to the second communication device, so that the first communication device and the second communication device establish the Bluetooth connection. Wherein the reply signal may be a bluetooth connection setup request message.
When the relation between the time length required by the first communication device to execute a part of tasks and the time length required by the second communication device to execute the tasks does not meet the preset condition, the first communication device determines not to establish Bluetooth connection with the second communication device and does not send a response signal, so that the first communication device does not establish Bluetooth connection with the second communication device.
Fig. 5 is a flowchart illustrating a bluetooth communication method according to a fifth embodiment of the present invention. On the basis of the first embodiment described above, the step 120 includes:
step 1211: the first communication device determines the actual time length of the second communication device for executing the partial task according to the time length required by the first communication device for executing the partial task and the time length of the second communication device capable of executing the partial task. Wherein some of the tasks include a scan task.
In one embodiment, after broadcasting the information packet, if the second communication device does not receive or approve the request of the communication device except the first communication device for reserving the idle resources and the idle time, the time length of the part of the task can be the idle time length indicated in the broadcast message; if the second communication device receives a request for reservation of idle resources and idle time by a communication device other than the first communication device after broadcasting the information packet and grants the request for reservation of idle resources and idle time by the communication device other than the first communication device, the length of time that the second communication device can perform the partial task is the length of time that is idle indicated in the broadcast message minus the length of time that is reserved.
When the time length of the second communication device capable of executing the partial task is longer than the time length of the first communication device required for executing the partial task, the actual time length can be the time length of the first communication device required for executing the partial task; when the time length of the second communication equipment capable of executing the partial task is less than the time length of the first communication equipment required for executing the partial task and the difference between the two time lengths is less than a preset value, the actual time length is the time length of the second communication equipment capable of executing the partial task;
step 1212: sending a notification message to the second communication device, the notification message comprising: indication information for indicating the second communication device to perform the portion of the task, and indication information for indicating an actual length of time for the second communication device to perform the portion of the task.
Optionally, the method further comprises: determining a particular channel for which to perform a scanning task; when the specific channel is plural, determining a time length for each specific channel; the actual length of time is equal to the sum of the lengths of time for each particular channel.
Wherein the indication information for indicating the actual time length for the second communication device to perform the part of the task includes: indication information indicating specific channels for which the scanning task is to be performed and a length of time for each specific channel.
Optionally, the notification message in step 1212 further includes: indicating information indicative of a desired perform-ance function, the desired perform-ance function including at least: and a function of filtering the search result obtained by executing the scanning task. The excel function may further include: and an address resolution function.
Optionally, the notification message in step 1212 further includes: indication information indicating the number of searches, the indication information indicating the number of searches indicating how many devices the second communication device has searched before actively reporting the search result to the first communication device.
Optionally, the notification message in step 12012 further includes: and the communication time interval indicates that the first communication device sends a message to the second communication device at a preset time interval so as to check whether the second communication device completes the part of the task.
Optionally, on the basis of the foregoing embodiment, before step 130, the method further includes:
step 130 a: the first communication device checks whether the second communication device has completed part of the task through the bluetooth connection.
In an example, the first communication device may check whether the second communication device completes a part of the task at a preset time interval.
In an example, before the step 130a, further comprising: the first communication device maintains a bluetooth connection with the second communication device. It should be noted that step 130a and the bluetooth connection maintenance are both performed before step 130.
In an embodiment, the first communication device may check whether the second communication device completes a part of the task in a CSB manner. In other embodiments, the first communication device may check whether the second communication device completes a part of the task by using an advertisement extension mode.
Fig. 6 is a flowchart illustrating a bluetooth communication method according to a sixth embodiment of the present invention. The bluetooth communication method is executed by a second communication device, and the second communication device can be a bluetooth chip or a combined chip (including a bluetooth module and a wifi module), or a device including the bluetooth chip, or a device including the combined chip, such as a smart phone.
In an example, the second communication device may determine whether to perform the bluetooth communication method in a preset manner to determine whether to assist other devices in performing some tasks, for example, Setting UI/API/host Setting/tci command/hci command. For example, the second communication apparatus may set the second communication apparatus to execute the bluetooth communication method through an tci _ colorloader _ enable command. Wherein the Host Layer of the second communication device transmits tci _ colormaker _ enable command to a Link Layer (LL) to execute the bluetooth communication method.
Specifically, as shown in fig. 6, the bluetooth communication method includes:
step 210: the second communication device establishes a bluetooth connection with the first communication device.
The second communication device may be in a state where the task is not being performed or in a state where the task is being performed.
